Patented Mar. 7, 1933 PATENT OFFICE ROBERT C. SCHEMMEL, OF AUNION CITY,INDIANA FINISHING WELT appuation mea'Juiy 8,'1929. serial No. 376,789.

My present invention relates "to improvements in welts, bindings,mouldings and finishing strips used in trimming automobile bodies andtops and `especially'in upholsterin the interiors thereof.

uch welts are commonly made of a base portion on which are superposedtwo or more longitudinal beads encased in a continuation of the fabricmaterial which forms the base portion, for the purpose of concealing,when the welt is in linal applied position, the nails, tacks or otherfastening means employed to secure the welt to the structure to betrimmed. Such welts are known as blind nail welts, A and since theissuance of United States Letters Patent No. 1,226,600 to me on May 15,1917, have been made in a variety of shapes and types and of -manydifferent materials.

It is frequently desirable to provide welts with bead coverings ofcontrasting colors to harmonize with an automobile interior done in twocolors, or, when the welt is to be applied to the outside top of avehicle, to produce a trimming in a plurality of colorsV and/ormaterials which will harmonize with the different colors of the bodyfinish and upholstery.

In all the welt constructions of the prior art with which I amacquainted, the several A beads which are attachedto the welt baseportion are necessarily encased or enveloped in a single continuousstrip of covering material. When, therefore, ithas been desired to v iproduce a welt having its several beads enclosed in fabric of dissimilarmaterials or of contrasting colors, it has been necessary to apply apaint or dye to the bead covering of the finished welt to simulatedifferent ma- "'50 to be concealed from view when the welt is in itsapplied finished position on the supporting structure to be trimmed.

lVith lthese and other objects in view, my present invention consists,in certain forms y of embodiment selected by way of exelnpliication, inthe novel welt structure illustrated in the annexed drawing, describedherein and particularly pointed out in the appended claims. l

In the accompanying drawing which 69' forms part of this application forLetters Patent, and in which the same reference numerals indicate likeparts in the several views,

Figure 1 is a perspective view, inwsection at one end, of one type ofwelt constructed 63 according to the principle of my present inventionand y Y Figs. 2 and 3 are similar views of two other types of-weltillustrating further applica- A, tionsof the principle of my presentinven- 70 tion. v

Referring to the drawing, the reference numeral 1 thereon designates thecustomary relatively large half round bead which coacts with one or moresmaller beads 2, in the types of welt which I have chosen to illustratean applicationV of my present invention, to concealthe `tacks or otherfastening means used tosecure the welt in place on the supportingstructure to be trimmed. 3 indicates a 8g fillerstrip havingincorporated therein pliable metallic weft strands which is secured tothe large bead and anchored in the base portion of the welt to provideapliable hinging member to hold the large bead down upon S' the-baseportion after the fastening tacks have been driven home, as particularlydescribedand covered in my previously issued United States LettersPatent No. 1,719,729, dated July 2, 1929. By the term base por- 93 tionI referto the assembly of parallel, contacting fabrics disposedunderneath ythe hinged bead and intended to immediately overlie thestructure to be trimmed. vThe large bead 1 is encasedin a flexible 9fabric covering 4 of any desired material and color, which, according tomy present invention, terminates along any convenient lines in the baseportion of the welt. In the drawing. 1.1m@ indicated the terminal edgesof 10 the fabric covering 4 by the reference numeral 5. It will be notedthat in the case of each of the different types of welt shown in thedrawing, the covering 4, before terminating in the edges 5, is disposedin two parallel, spaced apart layers in the base of the Welt.

The smaller bead 2, whether occurring singly or doubly in the weltsshown in the different figures, is encased in a covering fabric 6, whichin the case of each welt is continued into two parallel, spaced apartlayers in the base of the welt to terminate in the edges 7.

Unlike the bead coverings of the prior art, which are single unitarypieces for all the beads of a given welt, the covering 6 of a weltconstructed according to the present invention, as will be noted byreference to the drawing, is a distinct and separate piece of fabricfrom that forming the covering 4. The several beads of a single weltbeing there fore encased in as many distinct and different pieces offabric, it is obvious that in the production of a welt according to thepresent invention, the coverings 4 and G may be formed of differentmaterials, or of the same material in dierent colors, to achieve theobject of this invention in an entirely satisfactory and inexpensivemanner. It will also be apparent that the hereinbefore described methodof uniting the different fabrics in the base portion of the weltprovides an effective concealment of the seam from view and a means ofprotection therefor against accidental loosening. It should be observedthat the Various fabric components of the base portion are preferablycemented together, according to the common practice in welt making.

While I have shown and described my present invention in connection witha. limited number of different types of finishing welts, all of whichembody the pliable wire wefted fabric forming the subject of my priorPatent No. 1,719,729, it is to be understood that the selection of thesewelts is only by way of illustration of my present invention. Thepresent invention is applicable to many other and different types ofwelts, being capable of incorporation in any welt having a base portionand more than a single superposed bead. The appended claims aretherefore to be construed broadly and without limitation to the specifictypes of welts herein shown and described.

Having thus described my present invention what I claim and desire tosecure by Letters Patent is:

l. A blind nail finishing welt comprising a pair of spaced apart basefillers, a base fabric encasing said fillers and having a free edgetherebetween positioned close to one of the fillers, a flap filler, a.separate strip of fabric encasing said flap filler and having its freemargins extended from one edge of the flap filler, then folded backbeneath the flap filler, terminating in interitted relation with thefree edge of the base fabric, and a line of stitch ing passing throughthe base and flap fabrics adjacent the free edge of the base fabric tounite the base and flap securely together in hinged relation near saidlast mentioned base filler.

2, A blind nail welt including a flap bead and a base bead, a fabricencasing the flap bead and terminating beneath said bead in a pair ofparallel plies, a separate fabric encasing the base bead having both ofits margins terminating beneath said flap bead in parallel interfittedrelation with the margins of said flap bead-enclosing fabric andcooperating therewith to form a base having at least four plies, and aline of stitching uniting said four plies near one edge of the fourplyportion of the base and forming a hinge connection for the flap bead andbase.

In testimony whereof I afliX my signature.

ROBERT C. SCHEMMEL.
